I think I have the server side of corona M8 running on OS X. Here are
the current instructions on how to hack it ...

Download Eclipse 3.3M5 for OS X
Download the server all in one for Linux --- yes, Linux
Navigate to the eclipse directory in the Linux distro
Delete eclipse and eclipse.ini
Copy eclipse and Eclipse.app from the OS X distro to the eclipse
directory in the Linux distro
Copy the following plugins from the OS X distro to the eclipse plugins
directory in the Linux distro

Seems to be OK. For some reason it wasn't able to start it
"non-persistently", but the final info says it has been started. To
double check you can type "ss" in console and check if
org.eclipse.corona.collaboration.ecf is active.
